Solution Overview

Problem

Transaction cards are vulnerable to unauthorized use, leading to fraudulent activities such as accessing secure areas, making financial transactions, and redeeming rewards, as they lack effective verification methods to ensure only authorized users can engage in transactions.

Innovation Solution

Incorporating sensors to measure movement and determine a user's gait, comparing these measurements to a stored gait signature to authenticate the user, thereby enabling or disabling transaction card functions based on authorization.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional transaction cards are used without additional verification methods, then ease of operation is maintained, but security and reliability are compromised due to vulnerability to unauthorized use

Engineering Contradiction:

ImprovesecurityVSAvoidverification method complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent replaces traditional mechanical/card-based verification with a sensor-based gait analysis system. Motion sensors capture the user's walking pattern, and processors analyze these patterns to authenticate identity, substituting physical card verification with biometric gait recognition.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces gait signature analysis as an intermediary verification layer between the user and the transaction card system. The gait signature acts as a mediator that bridges physical card possession with authorized user verification, adding a layer of authentication without requiring direct user interaction.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If motion sensors and gait analysis are added to transaction cards, then security is improved, but device complexity and manufacturing difficulty increase

Engineering Contradiction:

Improveauthorization verificationVSAvoidcard manufacturing

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The patent makes the transaction card multi-functional by integrating both traditional card functions and new gait analysis capabilities into a single device. The card serves as both a physical authentication token and a biometric sensor platform, eliminating the need for separate verification devices.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent combines multiple functions into the transaction card: traditional card identification, motion sensing, gait analysis, and authorization verification. By merging these functions into a single integrated system, the patent reduces the need for multiple separate devices and simplifies the overall verification process.

Inventive Principle:

Principle #5Merging (Combining)

AI summary

An example transaction card may include a sensor to measure movement of the transaction card and one or more processors to monitor the movement of the transaction card via the sensor during a tracking period; determine measurements of a gait of a user during the tracking period from the movement of the transaction card during the tracking period; compare the measurements of the gait of the user during the tracking period and a gait signature associated with the transaction card; and/or perform an action associated with the transaction card based on a result of comparing the measurements of the gait of the user during the tracking period and the gait signature.
